Examples of org.eigenbase.reltype.RelDataTypeField

org.eigenbase.reltype.RelDataTypeField
RelDataTypeField represents the definition of a field in a structured {@link RelDataType}.
Extends the {@link java.util.Map.Entry} interface to allow convenientinter-operation with Java collections classes. In any implementation of this interface, {@link #getKey()} must be equivalent to {@link #getName()}and {@link #getValue()} must be equivalent to {@link #getType()}.
